Yes and No.
You can’t change ethernet mac as far as I know. If somebody figured out how, let me know. But you definitely can for wlans.
Yes, you can change for wireless too.
in “/interface ethernet set ether1” you can set the mac address of ethernet interfaces.
That is good to know.
Can you add multiple mac adresses to the same ethernet port?
it`s working, thnx 
ccr, no you cannot.
will this be possible in the future ? I kind of need it for
